Jquery + ASPajax solves Chinese garbled characters

When creating a website, the Simplified Chinese version of gb2312 is set as the website code because the website was not designed so much. It is a normal event to use gb2312 Encoding As a Chinese character, and there is no major problem in building a website, including compiling JSAjax by yourself. As Jquery becomes popular, I gradually like Jquery to operate D.

When creating a website, the Simplified Chinese version of gb2312 is set as the website code because the website was not designed so much.

It is a normal event to use gb2312 Encoding As a Chinese character, and there is no major problem in website construction, including compiling JS Ajax by yourself.

With the popularity of Jquery, I gradually liked Jquery's method of DOM operations. Later, I used Jquery files as a public JS library for the whole site.

Jquery's Ajax is also quite useful, because it is a public file, so you don't have to write any XMLHTTPrequest objects for every page that requires Ajax, so you start to use Jquery's Ajax.

Some problems are found during use:

The first problem is load, which is easier to cache than Get, that is, the output content is the same every time,

This is a good solution. Simply add a random number after the request URL, so that the URL is different and will not be cached.

The second problem is the garbled problem, which is quite time-consuming. After a while, I have come up with two solutions and record them to avoid forgetting them.

Method 1:

Encode the requested page as a UTF-8 file and set <% @ LANGUAGE = "VBSCRIPT" CODEPAGE = "65001" %> the server encoding to 65001 to indicate UTF-8, finally, the output code on the page is also set to UTF-8, that is, response. charset = "UTF-8", such as encoding, can solve the garbled Problem

<% @ LANGUAGE = "VBSCRIPT" CODEPAGE = "65001" %>
<%
Response. Charset = "UTF-8"
%>

Note that the page must be saved as a UTF-8 file. Otherwise, the whole page will be garbled!

Method 2:

The second method is to modify the jquery file!

I use Version 1.3.2. This is an example!

One of the most important methods for Jquery to handle ajax is ajax: function (s ){}

Whether it is $. load, $. get, $. post is finally processed in this method. No matter what else, you can directly find it. Why does Jquery convert all our passed parameters into UTF-8 encoded data,

The data parameter passed by jquery ajax is finally passed to the param: function (a) {} method for processing,

Jquery param is written as follows:

Param: function (a) {var s = [];
Function add (key, value ){
S [s. length] = encodeURIComponent (key) + '=' + encodeURIComponent (value );
};
// If an array was passed in, assume that it is an array
// Of form elements
If (jQuery. isArray (a) | a. jquery)
// Serialize the form elements
JQuery. each (a, function (){
Add (this. name, this. value );
});
... Is not stuck.

You can see the code s [s. length] = encodeURIComponent (key) + '=' + encodeURIComponent (value.

This is the reason for garbled characters, because the encodeURIComponent method is to encode the characters according to UTF-8 encoding and URI components (you may not understand it)

Let's improve this so that he can also perform URI Encoding Based on gb2312.

Var CharsetUtf = true;
Try {if (a. ParamCharset | a. ParamCharset = "gb2312") {CharsetUtf = false ;}} catch (e ){};
Function add (key, value ){
If (CharsetUtf)
{S [s. length] = encodeURIComponent (key) + '=' + encodeURIComponent (value );}
Else
{S [s. length] = escape (key) + '=' + escape (value );}
};

This is a simple modification. The principle is to define a variable to determine which character encoding is used for URI encoding.

If it is true, press UTF-8. If it is fales, press gb2312;

The default value is true. UTF-8 is used for processing!

Let's make a judgment!

Try {if (a. ParamCharset | a. ParamCharset = "gb2312") {CharsetUtf = false ;}} catch (e ){};

The code indicates whether the passed data a has the ParamCharset attribute. If yes, it determines whether it is equal to "gb2312". If yes, change CharsetUtf to false;

If no, it is not processed.

Try catch: This prevents data errors from being processed in UTF-8 format. To prevent attacks.

Well, I have written so much. Now let's call it and try:

$. Post ("/zhanHui/ajaxAsp/SearchPageZuiXin. asp"
, {SPageSize: pPageSize, page: pPage, ajaxContent: pAjaxContent, ParamCharset: "gb2312 "}
, Function (data ){
}, "Json ");

According to the above Code, as long as we add a ParamCharset: "gb2312" to the data parameter during the call"

This parameter is passed into the data of gb2312. It is useless to pass this parameter, that is, it is passed into a UTF-8 data.
